Small-board computers (SBCs) are getting more and more powerful. The Raspberry Pi 3 (RPi3), which just came out in February of this year, is a case in point. This latest in the Rasp Pi line now has four cores running at 1200MHz with 1GB of RAM and on-board WiFi and Bluetooth. If you need even more power in a small computer, however, you are not left wanting. In this issue, we look at three SBCs with more cores, more memory, more ports, and more possibilities.
